Motivation, Reasoning and the Proposed Proposition of EBG structures and Application of Dumbbell shaped EBGS as BPF

Motivation, Reasoning and the Proposed Proposition of EBG structures

From the intensive literature survey it is clear that the inclusion of EBGSs / dumbbell shaped EBGSs improve the performance of microwave components and devices significantly. From the performance of novel 2-D EBG structures for microstrip lines it is obvious that the performance is hindered by the optimized value of FF.

Realization of Band Pass Filter (BPF) and Non-uniform EBGS

 Realization of Band Pass Filter (BPF)

Each type of filters has different type of applications in the field of microwave communication system. There is a well defined formula deduced from the Bragg’s condition for circular shaped EBGS.

Performance of uniform circular PBGS Assisted BPF, Performance of reference BPF, Performance of BPF on 2-D array of uniform circular PBGSs, Performance of BPF on dense 2-D array of uniform circular PBGSs, Performance of BPF with three line uniform circular PBGSs, Performance of BPF with uniform circular PBGSs under two extreme 50 ohm lines, Performance of BPF with uniform circular PBGSs under all the lines Performance of BPF with uniform circular PBGSs under all the line

    Performance of uniform circular PBGS Assisted BPF

Theoretical results are produced for different geometries of uniform circular PBGS assisted BPF. To see the effect of uniform circular PBGS in harmonic suppression the performance of reference BPF is shown. Finally the insertion loss performances of a standard BPF and uniform circular PBGS assisted BPF are shown to compare the results.
